HAMMERING MECHANISM FOR BEADlNG-MACHINES.

SPECIFICATION forming part of Letters Patent NO. 624,426, dated May 2,1899.

Application filed March 6, 1899.

To a, whom it may concern.-

Be it known that I, QUENTIN W. BOOTH, of Rochester, Monroe county, NewYork, have invented certain new and useful Improvements in HammeringMechanism for Beading-Machines,of which the following is aspecification.

This invention consists in certain improvements specially applicable tothe well-known machines the object of which is to finish seamed edges,and particularly the seamed edges of shoe-uppers which are sewed wrongside out, such machines being usually called beading-machines.narilycomprise twonecessaryand cooperating e1e1nents'to wit, first, oneor more rapidlymoving turners the functions of which are to turn thelined upper to bring the right side out and to smooth and push out thescam, the latter function being particularly important in the case ofthe scalloped button-flies of ladies and misses shoes, and, second, ahammer which flattens out the turned seam.

The present improvements consist in an improved construction of thehammering lIlQOhm anism and are illustrated in the accompanying drawingsas applied to a beading-machine the general characteristics of which aresimilar to the machine set forth in United Stat-es patent to Peter W.Minor,No. 494, 259, granted March 28, 1893.

In the accompanying drawings, Figure 1 is a side view of the machine,partly broken away to show the interior construction; Fig. 2, a planview of the head of the machine; Fig. 3, a rear view of the head; Fig.4, a vertical cross-section in a plane indicated by the line 4 4 in Fig.2; Fig. 5, a sectional detail, and Fig. 6 a central vertical section, ofthe head.

A is the housing of the machine, B the drive-shaft, and O O therapidly-movingturners,which may have any of the motions known in theart, though preferably they have the movements of the tnrners set forthin the United States application of Irving E. Booth,

Serial No. 556,230, filed July 17, 1895. D is the upright hollowstandard or head, constituting an integral part of the housing A, whichsupports the movable hammer E, the anvil F, and the fixed hammer-guardG. The hammer E is rapidly rocked by means of the pitman H, which isconnected with it by Such machines ordi- Serial No. 707,939. (No model.)

' is pivotally mounted between vertically-extending ears 0 c, which areintegral parts of the upright standard or head D. Within these twoprojecting ears are carried brass bushes d (1, respectively, which areheld in place by means of screws e e,which tap through the upperportions of said ears. The hammer Eis secured by set-screw f to ahorizontal hammer-shaft I, which extends through and rocks in the brassbushes d d.

The anvil F which is a movable one is forked at its rear and upper end,as best shown in Fig. 2, and is formed with tubular sleeves or journals9 g, which straddle the ears 0 c of the head and surround and embracethe outwardly-projecting ends of the brass bushes d d, upon which theyrock, said projecting bushes constituting the journalbearings upon whichsaid anvil swings. It will be noted on reference to Fig. 4 that thehammer-shaft I extends outwardly as far as do the brass bushes, so astoafford a support for their projecting ends. By virtue of thisconstruction it will be noted that the anvil when it moves swings on thesame axis as does the hammer, so that no matter how the anvilis'adjusted the movable jaw has the same re lation thereto. It is not,however, essential that the anvil be pivoted about the same axis as thehammer but such construction is pre ferred. l

The anvil is cushioned in both directions by means ofindependently-adjustable coiled expansive springs J and K. The coiledspring J is located between the under side of the head of the anvil anda tension-regulating bolt L. This bolt L taps into the head D and islocked in any desired position of adjust ment by means of a lock-nut h.The spring J seats at its upper end within a recess 2' on the under sideof the anvil, and at its oppojecting boss 1 on said bolt, which alsoserves to maintain said spring J in position. The

adjusting-bolt L and the spring J are so arranged as to be substantiallyperpendicular to the outerworking face of the anvil F, so that theoutward thrust of said spring against the under side of said anvil issubstantially at right angles to said working face, so that said springtends to force the anvil toward the hammer, and said spring directlyopposes the stroke and impact of the hammer.

The anvil has an integral crank-arm M, eX- tending at substantiallyright angles to the working face of the anvil and which cooper? ateswiththeothercushioning-springK. This crank-arm carries at its outer enda socket N, a cross-section of which is shown in Fig. 5, and in whichsocket the spring K seats. This socket is interiorly screw-threaded, as

, shown in Fig. 5, and in it fits an adjustingscrew 0, which can beturned in an out, being provided with a nick m for this purpose,adapting it to be turned by a screw-driver. This adjusting-screw O canbe clamped in any position of adjustment, the socketN being for thispurpose slit along one side, as shown at 'n, and being provided withoutwardly-projecting ears 0, with which a bolt 19 and nut q cooperate.By means of said bolt and nut the socket may be clamped tightly upon theadjusting-screw as desired, so as to hold it in posit-ion. The outer endof the spring K seats against the inner face of the adjusting-screw O,surrounding a projecting tion substantially at right angles to the d.i-.

rection of the thrust of the other spring J. The tension of spring K isregulated by the adjusting screw 0. The position of the crank-arm M isnot necessarily at right angles. to the face of the anvil, since itcould be in any position about the axis around which the anvil pivots,the abutment P being correspondingly located. v

It will be noted that the two springs J K oppose each other, and bothare adjustable independently and at will. Thespring .I resists theimpact of the ham mer,and the other spring K maintains an initial strainon spring J. By suit-ably adjusting both springs the position of theanvil when the machine is at rest can be adjusted and maintained, sothat the minimum space between it and the opposing workingface of thehammerthat is, the space when the hammer most nearlyapproaches theanvil-.can' be adjusted and regulated at will, thereby adapting thehammer to operate upon materials of different thicknesses. By, suitableadjustment of both springs the anvil may be made more or less yielding,as desired, and

compensation for wear is readily secured. When the hammer is inoperation, the two springs cushion the anvil against the blows of thehammer and take up the backlash. The cushioningsprings are comparativelystiff, thereby affording a substantial support for the anvil and holdingthe anvil toits work, so that an efficient blow may be given to the seamwhich is being hammered; but at the same time the blow upon the seam isrendered elastic, so that there is no danger of crushing or abrading theseam. This construction also renders the hammer almost noiseless whilein operation.

While the anvil is shown arranged at an incline, it is obvious that thissame cushioning arrangement for the anvil could be used in case itsworking surface was arranged substantially vertical, as in the case ofthe arrangement shown in said I. E. Booth application, Serial No.556,230.

The interposition of the bushes d d between the anvil-journals g g andthe hammer-shaft I is important, because the bushes not only thusconstitute j ournal-bearings for both hammer and anvil, but also theyrelieve the 11ammer-shaftfrom the stress of the cushioningsprings, thusdiminishing the power required to move thehammer and relieving thehammer-shaft from wear.

I do not claim any feature or combination of features which is common tothe machine herein set forth and to that set forth in the said I. E.Booth application, Serial No.556,230, and especially I make no claim 'toa hammer in combination with a cushioned pivoted anvil, nor to aswinging hammer in combination with a cushioned adjustable anvil pivotedconcentrically with said hammer, nor to a swinging hammer in combinationwitha pivoted anvil adjustable to and from the hammer and pivotedconcentrically therewith, nor to the combination, of a hammer, a movableanvil, an'elastic cushion to resist the impact of the hammer, and asecond elasticcushion, which maintains an initial strain on the firstcushion.

I claim as my invention-- 1. The combination of a hammer, a movableanvil, and independently-adj ustable cushions for cushioning said anvilinopposite directions, substantially as set forth.

2. The combination of a hammer, a movable anvil, and independently-adjustable cushioning-springsactingupon said anvil in opposition to eachother, substantially as set forth.

3. The combination of a rocking hammer, an anvil movable concentricallywith said hammer, and independently adjustable cushioning-springs actingupon said anvil in opposition to each other, substantially as. setforth.

4. The combination: of a rocking hammer, an anvil movableconcentricallywith. said hammer, said anvil having a crank-arm with a split, socketinteriorly screw-threaded, an

adjusting-screw fitting within said socket,

means for clamping said socket upon said screw, a fixed stop, anexpansive spring interposed between said screw and stop, an adjustablebolt behind the anvil-head, and an expansive spring between said boltand head, substantially as set forth.

5. The combination of a rocking hammer, a rock-shaft therefor, aswinging anvil, bushes interposed between said shaft and anvil andconstituting bearings for both, and cushioning-springs acting upon saidanvil in opposition to each other, substantially as set forth.
